SGPLOT xaxis notification message

[flyingbear]

Hi,

I'm running SAS 9.4 on Windows.  I'm receiving this notification message when I run the following code.

NOTE: Time axis can only support date time values. The axis type will be changed to
LINEAR.

data aaa; set bbb;
format date year4.;
pct_diff = (f_&var/f_&var._2017-1)*100;
run;

proc sgplot data=aaa noautolegend;
title "Percent Difference: 2018/2017";
band y=pct_diff lower="01oct2017"d upper="30sep2044"d / fillattrs=(color=blue transparency=0.95);
series x=date y=pct_diff / lineattrs=(color=blue thickness=2);
xaxis grid values=("01jan2012"d to "01Jan2020"d by year) display=(nolabel);
yaxis grid label="Percent";
run;

The graph is drawn properly since, I think, my data is evenly spaced so linear has no impact.  But it would still be nice to clean up my log file and also to understand what is causing this.

Can anyone help?  Thanks in advance,

Jonathan

Try adding interval=Year to your XAXIS statement?

Thanks, Reeza. I was being stupid! See below.

I realized that although the variable DATE was formatted as a year, it was just a numeric variable.  Once I constructed it (using the MDY function) as a SAS date variable the notification message no longer displayed.
